|Almost certainly too low. *Help out your fellow boaters! Add a comment or report about runnability at various reported flows. Virtual gauge based on relative areas. Top Silver is 16.8 sq.mi. above E.Br., whereas working gauge has 64.7. Correlation is not assured.|
If the rivers in the L'Anse area are running a tad too high, you may be looking for something in the upper parts of drainage areas. This may fit the bill (if the access roads are passable). The main action (and the steepest mile) is just downstream of the listed put-in. Gradient peters out quickly after the first mile-and-a-half, so it is likely that boaters will opt for a take-out short of the full reach.
Specifically, the first full mile drops about 232 FPM. (The first half-mile drops the equivalent of 250FPM, the second half-mile about 215FPM equivalent.) The second full mile, gradient eases to about half of that (~115 FPM). Overall gradient from 1.5 miles to the end of the listed run is about 25-30 FPM. So, there will be lots of easy cruising (if it is not too snag filled), with a good assortment of random decent features, and ending with some great action just above the normal put-in for the "Upper Silver" run.

I have also heard some folks refer to this as the 'Yooper Silver' (a take-off on both 'upper' and the common term for residents of the Upper Peninsula of Michigan as "Yoopers" -- U.P.-ers). My naming here is a take-off on both the convention of designating a section '0' (zero) upstream of what had previously been labeled numerically as section 1, and with a nod to the old old TV series "The Lone Ranger" (ok, showing my age here) which had the masked hero astride his horse, Silver. The horse reared up ready to gallop off, and the voice-over exclaimed "... Hi-Oh, SIlver . . . Away!" (As in the tag from the following episode, courtesy of YouTube.)
Various online maps have this marked in various locations, especially as one 'zooms' to different levels. (And I've seen at least one single map with it marked in two different locations within the same resolution/zoom!) My best guess (based on gradient lines and aerial views) puts it about 1/3rd-mile down from our listed put-in. Be prepared to scout!
A ford (low-water river-crossing) could be a choice access (either as put-in to skip the upper falls, or shortest convenient take-out to just run the steepest mile). However, another good shot of gradient exists not far downstream.
Steepest gradient is done by about a half-mile above, so this may be the take-out of choice for those wishing to try for other runs in the same day.
USGS lists a sampling site showing drainage at this point as 16.8 square miles.
